Resumen
The invention fits into the sector of wood technology, in the inspection of wooden elements and structures. It is a device that, coupled to a commercial drilling machine, extracts a volume of wood determined in the form of chips. These allow estimating the density of the piece of wood tested by the relationship between its mass and the volume of the hole generated. The chips that are produced during the drilling are collected in a single-use filter paper bag. The technique of use involves fixing the diameter of drill and the depth of drilling thus establishing a known volume of extraction, for the estimation of the density of the wood. In this way it can be correlated with its physical-mechanical properties. (Machine-translation by Google Translate, not legally binding)
